Technical Field

[0001] The utility model relates to the technical field of continuous belt conveyor equipment, in particular to a continuous belt conveyor extending device and a continuous belt conveyor. Background Art

[0002] Continuous belt conveyors are widely used in the tunnel construction industry due to their high slag discharge efficiency, strong slope adaptability, safety and environmental protection, intelligent control, and easy maintenance. The most significant feature of continuous belt conveyors is their ability to extend the tunnel boring machine without stopping. Therefore, the extension device is crucial. Currently, the sliding shoe extension device is more commonly used in actual projects, but this device has a complex structure, and the weight of the sliding shoe can easily cause the belt conveyor bracket to deform, which is detrimental to the stability of the continuous belt conveyor's overall structure. In addition, the belt conveyor bracket consists of a longitudinal beam, an upper roller group, and a lower roller group. Installation must be carried out on both sides of the extension device. When the extension device is close to the tunnel wall, there is insufficient working space for personnel, making operation inconvenient.

[0003] Based on the above, there is an urgent need to provide a continuous belt conveyor extending device and a continuous belt conveyor to solve the problems existing in the prior art. Utility Model Content

[0032] Example

[0033] See also Figures 1 to 6 This embodiment provides a continuous belt conveyor extension device, including an extension platform component 1, an assembly platform component 2 and a hanging bracket component 3. The extension platform component 1, the assembly platform component 2 and the hanging bracket component 3 are all arranged on a rear supporting trailer frame 4; the extension platform component 1 is used to provide support for a new belt conveyor bracket, and its setting position corresponds to the existing belt conveyor bracket. The hanging bracket component 3 is adjustably set on one side of the extension platform component 1, and the assembly platform component 2 is set on the other side of the extension platform component 1 at a position opposite to the hanging bracket component 3.

[0034] See also Figure 1 In this embodiment, the extension platform assembly 1 includes an extension platform 1.1 and adjustable legs 1.2. The adjustable legs 1.2 are disposed below the extension platform 1.1 and are used to support the extension platform 1.1 and adjust its height. The adjustable legs 1.2 are provided in multiple groups symmetrically along the length of the extension platform 1.1. Hollow structures are formed between the multiple groups of symmetrical legs to facilitate the passage of the conveyor belt 6. In this embodiment, the adjustable legs 1.2 are preferably adjusted via an adjustment screw disposed between the legs and the extension platform 1.1. By rotating the adjustment screw, the height of the extension platform is adjusted to ensure that the newly installed belt conveyor support is at the same height as the existing belt conveyor support. In this embodiment, the height of the extension platform can also be adjusted using any of a hydraulic cylinder, a pneumatic cylinder, and an electric push rod.

[0035] In this embodiment, the tail of the extension platform 1.1 (the side that connects to the existing belt conveyor bracket) is provided with a sinking section 1.3, see Figure 1 The sinking section 1.3 is an L-shaped connecting plate, which is used to place the lower roller group 5; a protective plate 1.4 is provided above the sinking section 1.3, see Figure 1 and Figure 6 (b) The protective plate 1.4 is located below the conveyor belt 6 and is used to protect the conveyor belt 6.
